Level Measurement for IMO Type C Tank Single shell for LPG
Marine Level measurement using modern radar technology increases safety and efficiency
Solutions to address customer challenges with marine level measurement
The use of LPG in the marine industry has been topical for a few years and is most used on LPG carriers. With changing trends, the new fuel applications are more demanding when it comes to level measurement compared to conventional fuel tanks. For new applications there is no solution to fit them all, instead a verity of solutions is needed.
Single shell type C tanks with a tank volume of less than 1000 m3, and operational temperature and pressure at -48°C to 20°C and up to 20 bar and less than 15 m in height, are feasible to be used for LPG. Radar technology is ideal for this application since it has a vertical cold box with process connections on top of the tank. Solutions used for this applications must be IGF code compliant and approved by marine class societies.

Your profitability and reputation as an LNG operator demands buyer-seller agreement accuracy. The Rosemount TGU 53 Tank Radar Gauge is built for the task. The radar transmission is guided through a full length still pipe measuring the surface of the product and the patented array attenuator ensures accurate readings from the very bottom of the tank. Using the accurate and reliable TGU 53 you can perform your cargo transfer with complete trust. With dual channel technology primary and secondary level measurements are enabled by two independent radars, yet in one housing and a single still pipe installation. Single tank penetration makes for affordable new and retrofit installation.
- 5th generation of proven, industry-leading marine radar performance
- Minimized footprint and efficient installation with all CTMS functions in a single housing
- Safe operating redundancy with dual radar channel technology
Reference Accuracy

To meet regulations regarding emissions, many vessels are transitioning to using liquid natural gas (LNG) or liquified petroleum gas (LPG) as their primary fuel source due to their low sulfur emissions. However, this shift presents challenges in finding a marine supplier that offers a complete solution for level, pressure, and temperature measurement devices capable of operating under extreme conditions. This complete multi-instrument single flange solution can be configured to meet the needs of a future fuel tank application, ensuring safe and compliant operations.
- All instrumentation on the same flange makes it is easier for the design engineer to create the tank design
- Same configuration tool makes it fast and easy to configurate all instruments
- Same supplier for all instrumentation and the flange reduces supplier complexity
